Previous studies of the driving times of shopping center patrons have not examined the effect of limited access highways.
This study analyzed the impact of interstate highways on the driving times of 204 shoppers at three medium-sized regional
shopping centers. Those shoppers indicating usage of interstate highways to reach their shopping destinations were significantly
more likely to incur travel times greater than fifteen and twenty minutes than those not using the available interstate roads.
In predicting the drawing power of these shopping centers, factors besides mass were found to be useful. These include square
footage of shopping goods, stores, and number of parking places. 相似文献

Question order effects in taste testing of beverages 总被引:1,自引:0,他引:1
The effect of order position has been demonstrated in marketing research, sometimes compromising survey results. This paper
studies the influence of order position in product taste trials of carbonated beverages using a sequential monadic design.
The authors measure attitude ratings across product trials rather than across products to examine the effect of order position
on preference ratings. 相似文献

The efficiency of a research design may be measured in terms of the degree to which knowledge is enhanced within given resource
constraints. Thus, two different types of research design, even though they contain the same number of expected observations,
may differ considerably in the amount of information provided. An example is the number N of 32 observations obtained with
an analysis of variance witheither 2 factors, 2 levels per factor and a replication of 8or 4 factors, 4 levels per factor and a replication of 2. We analyze and compare the relative efficiencies of regression and
variance analysis models and their implications to research strategy development. Three major considerations are evaluated:
(1) short versus long time horizon (interval until effects of a decision are realized), (2) small versus large cost of erroneous
rejection of the Null Hypothesis and (3) gross versus refined stage of development of the research study. A set of general
guidelines towards improved designs is developed. 相似文献

An attempt is made to bridge the gap between the theorists and modellists approaches to the conceptualization of theoretical constructs. The former approach assumes that every theoretical construct has a surplus meaning over and above its operationalization and measurement as a concept. The latter approach denies this: it only accepts theoretical constructs as functions of relations between observations, i.e. measured concepts.This gap can be bridged by explicating the definition of a theoretical construct before making attempts to operationalize and measure it. An explicated definition should cover all relevant aspects (or: facets) of a construct, systematically brought together in an ideal type model. On this basis, operationalization of the construct can be directly linked to model elements, so that any possibly remaining surplus value is made explicit. The distance between theoretical construct and the measured concept can then be made as small as seems feasible; in principle, the distance can be made zero. The manner in which conservative ideology is conceptualized in a longitudinal research project in the Dutch electorate is presented as an example of this strategy. 相似文献

This paper extends the mixed estimation technique to handle a case in which the coefficients of a set of linear constraints are known nonlinear functions of an unknown parameter vector for which an extraneous unbiased estimate is available. This novel form of the mixed estimation technique is illustrated by applying it to the Bass innovation/diffusion model of new product growth. It is suggested that this is superior to the traditional method whereby managerial intuition is incorporated into this type of model, and is an attractive alternative to recently-suggested Bayesian methods.I thank an anonymous referee for helpful comments and references. 相似文献
